XYZ Racing Street Advanced Coilovers — Toyota SIENNA IV XL40 2020-2026

The XL40 Sienna’s switch to a hybrid-only drivetrain and TNGA-K platform brought genuine structural improvements to the fourth-generation model – but its factory suspension tune remained dialled deep into comfort territory, prioritising three-row passenger compliance over the cornering manners that actually make a long-wheelbase MPV enjoyable to drive. For the Sienna owner who actually enjoys the driving seat – and there are more of them than the segment’s reputation suggests – that tuning leaves measurable scope for improvement.

This XYZ Racing Street Advanced coilover kit addresses the specific compromises baked into the XL40’s road-biased setup: body roll through faster bends, a ride height that underuses the available wheel-arch clearance, and damping that cannot distinguish between an empty motorway run and a fully loaded family trip. All three are adjustable here.

What this coilover does for your 2020-2026 Toyota SIENNA IV XL40

The XL40’s taller body and elevated centre of gravity make body roll the dominant sensation through quicker corners – reducing ride height directly reduces the leverage working against the chassis in those moments. The Street Advanced’s 720-way damping range provides genuine granularity across the XL40’s operating conditions: softer settings preserve the absorbent ride quality that makes a three-row MPV liveable on a daily run; firmer settings tighten body motion for unloaded, faster-paced driving. Adjustable height works within the XL40’s wheel-arch geometry, allowing a lower, more intentional stance without the clearance issues that follow from dropping a tall MPV on fixed lowering springs.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most widely adopted coilover range – a kit developed over several years by the XYZ professional team and validated through competitive race use across events worldwide before being signed off for road-going specification. The product is intended for normal road driving and track-day sessions, covering the spectrum from daily-driver comfort to more spirited occasional use. Its headline capability is 720 damping adjustment settings, accessible through a single point without removing the wheel, providing control over compression and rebound characteristics across the full range the XL40 encounters. That adjustment depth is what distinguishes the Street Advanced from a conventional spring-and-shock replacement: a coilover that can be genuinely softened for a loaded family run or firmed for a solo blast on an empty road.

Fitment for the Toyota SIENNA IV XL40 (2020-2026)

This kit is built for the Toyota Sienna XL40 fourth-generation chassis, covering models produced from 2020 through 2026. The XL40 designation spans the entire current generation, which introduced the hybrid-only powertrain and the move to TNGA-K architecture. Confirm your build year falls within this window before ordering – the earlier XL30-generation Sienna uses different chassis geometry and is not covered by this kit.
